Zusammenfassung:	A coupon (170, 300) for replacing a cutout (172) in a hot gas path component of a turbomachine (100) is provided. In one embodiment, the coupon (170, 300) includes a body (180, 268, 304) having an outer surface (182,270, 304); and a plurality of grinding depth indicators (250) in the outer surface (182, 270, 304) of the body (180, 268, 304). In another embodiment, the coupon (170, 300) includes a body (180, 268, 304) having an edge periphery (200, 202) configured to mate with an edge periphery (200, 202) of the cutout (172), and at least a portion (210) of the edge periphery (200, 202) of the body (180, 268, 304) has a wall (305) thickness greater than a wall thickness of an edge periphery (200, 202) of the cutout (172). The embodiments may be used together or separately.
